Does Graviton bend light?

In the weak gravitational regime where the low-energy effective action holds,(linearized) gravity can be quantized, and we can treat graviton as quantum fields on a Minkowski background. One can also couple it to other fields (e.g. Maxwell) to obtain interactions terms.

The classical counterpart of graviton can be thought of as gravitational wave modes, which certainly perturb the background geometry. In the presence of graviton excitation, does it affect the geometry as the classical limit predicts? i.e. does free falling test particle’s trajectory get bent?

If so, with graviton excitations in superposition, do we get a semiclassical description of superposing geometries?
